 company for whom he designed a wheel/track light tank, the KH-50 (Kolo-Housenka). This design had roadwheels mounted on the drive sprockets and jockey wheels behind them to support the tracks. Despite impressive specifications for the period - 13 mm armour, 37 mm turret-mounted armament, and a 50 hp engine capable of driving the tank at 8 miles per hour (12.9 km/h) (on tracks) and 22 miles per hour (35.4 km/h) (on wheels) - it was rejected by the Czech army.

The army was, however, impressed by the hybrid wheel/track concept and commissioned further studies, which resulted in the KH-60 (1928–29) and the KH-70 (1930). In these two designs the engine power was increased to 60 hp and 70 hp respectively and a better system was developed for switching between track and wheel use which allowed a change in less than 10 minutes.

2 KH-50 prototypes were built, one of which was later converted to a KH-60 and the other scrapped. Actual production included 2 KH-60s to the USSR and 1 KH-70 to Italy
